Application filed March 4, 1911. Serial No. 612,225.

To all whom, it may concern Be. it known that I, ALFRED J. .ELLr a citizen of the United States, residing at lVoodclitf-on-Hudson, township of North Bergen, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in .Hollow Metal Door-Frames and the Like, of which the ,following, is a full, clear and exact description.

This invention relates to hollow metal door frames. and the like, and has for its object the simplification of such structures;

providing av hollow metal door frame, the parts of which may be readily assembled.

' The frame is preferably composed solely of straight elements. means being provided for uniting such members to form a unitary structure.

A further object of m invention is to provide novel means where y certain of such elements may be firmly locked in position in brick work or the like, said means being adjustable with respect to said elements for reasons hereinafter specified.

I further aimto secure a structure having great strength and rigidity with a minimum amount ofmaterial.

' ll'still further object of my inventionis to provide'means whereby, for example, in

a door constructedin accordance with the principles of my invention, a portion of the jamb forming elements thereof may be made substantially of uniform dimensions for various widths of jambs, such portions being zulapted' tointerlock with other jainb forming parts which may be of variablewidthslo the end that any desired. overall width of jamb may be furnished at a minimum cost of production and expense of .*-.nother object of my invention is to so fornrand dispose the several frame elements 'as to facilitate their assembly and to reduce the number of-bolts or likeuniting devices toagininimum.

, hose. and other objects of my'invention will-be hereinafter set forth and more particularly pointed out in theappended claims,

Referring to the drawings which forn a part hereof. and in wl. ch like refer nee characters nesignate like parts through at the several views: Figure 1 is an elevation J ofqa door frame constructed in accordance v with the principles of-my invention, the left hand side of the molding thereof being broken away to expose a, portion of the buck. Fig. 2 is a fragmentarysection of theframe shown in Fig. 1', taken on the line IIl.I,of said figure, the section being viewed as shown-by the arrows in Fig. 1. Fig. 3 is a detail fragment of sa l door frame, taken on the line IHIIl' elf Fig. 2. Fig. 4 is a fragmentary detail showing means for uniting the buck members; and Fig. 5 is a fragmentary detail of'a corner of the jamb. I

Referring to the drawings, the-vertical jamb sections have been broadly designated 1, and the corresponding horizontal jamb section 2. These jamb sectionsare preferably of the. same general configuration in both sect-ions 1 and 2, and are'each formed of two elements, as shown in Fig. 2, to wit, the main elementor part 3, and an auxiliary L-shaped part l. These elements are adapted to be interlocked longitudinally thereof as at 5, the particular connection "used being preferably that disclosed in my co-pending' application Serial No. 629,099,

filedv May 4, 1911. By reason of this.con-' st-ruction it. is possible to maintain the cross sectional dimensions of the elements 3 standard for various sizes of doors, regardless oflthe thickness of the 'wall to which the framehmay be applied, While the auxiliary elements l may be'of varying widths to accommodate various thicknesses of wall; the interlock ng connectlons being also 'standardl IThese connections are preferably positively interlocked; that is, the interlocked parts are so held together by the connections usedthateven Without the use of screws, "rivets, or the like, the parts cannot become inadvertently laterally-- displaced with respect to each other when in assembled relationship. By reason of this. the part 3 can be kept in stock while the usually. narrower parts or elementsh an l)0;l.l;l(lc 'up ate-required. This feature is oln'iously of great importance to the trade. in thatv it expedites the filling of orders'and also reduces the cost of shipment in many instances by reducing the weight of parts to be enprcssed. Parts 3 and however. when as sembled may be regarded as'a unit and \Ylll together he hereinafter referred to as a jamh section. 'lhcseyamb sections are provided "with suitable'molding sections. 6; and, when 1 assembled, are adapted to receive a door in the usual manner.

It will be noted that each jamb section, considering the elements seinbled to form a whole, is substantially U-shaped in'cross section, and the respective flanges 7- of such section are each adaptedto be received into a groove 8 which is formed in' a flange 9 of the buck 10; one of such flanges 9 extending laterally from either side of the body 11 'of'each buck forming part. In cross section each of these buck forming parts or buck-members is also substantially U-shape'd, and is formed preferably by bending sheet material into channelslike form and further bending or folding over portions of the flanges so formed upon ,themselves, was to provlde grooved flanges; 'itbe grooves 8 of which are preferably adapted to receive the flanges 7 of the jamb. sections quite snugly.

, Apertures or holes are provided in the. respective moldingsections, jamb flanges 7,

andibuck flanges 9, which when the parts are .in assembled relationship will be in alinement' and adapted ,for'the reception of suitable uniting or securing devices, such as'the bolts 12. Herein is a feature of considerable importance, in that the number of securing devices is reduced to a minimum.

The molding sections are preferably flanged: as at 13 so that the edges of these flanges may engage the respective .jamb flanges 7 The buck members are preferably secured to-' gather at the respective-corners of the buck in any suitable manner, as for example by means of the tongues 14' andcorresponding' 'slots 15,-and these members are firmly held in place 'when the wall has been erected therea'round by means of anchoring devices or plate 15. In my prior application above referred to, in'lieu of these anchoring plates,

tongues were struck-up out of the body of the buck members therein described, but I have found in practice that such securing means should preferably be adjustable longitudinally of the buck members, in order to accommodate the devicesto a brick wall,

for example, since therein the plane between courses of brick in which an anchoring device is to be disposed, may vary materially in elevation or level, owing to different thlckne'sses of mortar between the several tiers of brick. I have now therefore formed the anchoring elements separate and distinct from the buck members and have rendered the same adjustable longitudinally with respect thereto, by making suchmembers substantially L-shaped as shown in F gs. 2 and 3, and by slotting as at 16 the sides 17 of such plates which abut against the outer wall of a buck member. Theseranchoriug plates may hence be clamped at any-desire helght or along the length of a buck member by 3 and 4 as as-' means of bolts 18, and the wall engaging portions thereof are preferably corrugated.

as shown, in order to more firmly lock the same lntothe wall.

In erecting a door of this type, the sevthe cost of producing and assembling the same isreducedsubstantially to a minimum. It will be observed that when the parts are in assembled relationshipthat a portion of the i nterlocking connections 5 of the jamb sections will bear against the respective sections of the buck sothat the middle portions of said jamb sections are supported against inadvertent lateral displacement.

In conclusion, I particularly wish to point out that I contemplate various applications of my herein described invention, the door frame shown in the accompanying drawings being but one exemplification thereof,so that the said invention should only be limited by the scope of the/claims appended'hereto.
